Help have sick chicken and two dead not sure whats going on

its so awful when you cant find a vet that looks at chickens. I would say it sounds like either a respritory infection which needs abs. Tylan does not have an egg withdrawal period in the Uk I dont know about there. The other possibility is sour crop is her crop clear

 

Sounds like a respiratory infection.
Could you treat them all with antibiotic in the water.
You could probably get that at the feed store and follow package directions.

 

I'm sorry for your trouble. I don't know what your birds have but this website is pretty good. It lists all the respiratory diseases if you look through it. Good luck.

Tyan 50 administered sub Q. 1 cc per adult bird for 3-5 days should do the trick. Vet Rx on the beak as well.
Good luck!

 

So long as you don't ever sell any birds to other farms in the future, there is a pretty easy solution (though lots of posts on other threads will say to cull all your birds, but that is totally unnecessary if you don't plan on selling birds from your farm in the future). If you have a totally separate spot to put the sick ones, I would just keep the sick ones separated from the others. You should immediately disinfect the water container with bleach or oxine before refilling with clean water (for the birds in the healthy-pen). That will help keep the other birds from catching it. Then every night listen very closely to each bird in the well-pen, and look closely for any sign of running nose (especially the next few days since some might have already caught it and just not shown symptoms yet), and immediately move any birds with symptoms to the sick-bird area. Once the sick birds either die or recover completely (possibly taking a few weeks), I would go ahead and put them back together with the others and just keep watching closely each night for any others to get symptoms. The sick-pen could also benefit from a warm light to sleep under, and check for lice since that lowers their immune system.

The medication option: If you're particularly attached to one of the birds that gets sick, you can get the tylan 50 injectable $9.99 at feed store, and inject 0.5cc per day for 3 days into the meaty-leg-area of the sick bird. Once they are completely symptom-free you can wait a few weeks to put them back in the main pen, just to get the egg-withdrawal period out of the way before putting them back in the main pen. The tylan will help with just about anything respiratory, which is nice because it's virtually impossible to know exactly what type of infection it is, without necropsy and full tests which aren't really necessary if you don't plan to sell birds to other people.
